I was wondering if upgrading my K03 to a K04 is worth it? I am saying this because it's the only turbo that I can upgrade and not have to change my clutch, headers and everything else that goes along with a bigger turbo. I have a K03 with a GIAC chip right now. Would i be able to use the same chip if I simply removed my K03 and bolted on a K04? I'm further hesitant because apparenlty there is a lot more lag on the K04 so is it really worth it?
Thanks
